Hi,
a few last-minute remarks. I plan to merge this afterwards.

> Subject: [PATCH v2 1/2] ath79: add support for AirTight C-75
>
> AirTight Networks (later renamed to Mojo Networks) C-75 is a dual-band
> access point, also sold by WatchGuard under name AP320.
>
> Specification
> SoC: Qualcomm Atheros QCA9550
> RAM: 128 MiB DDR2
> Flash: 2x 16 MiB SPI NOR
> WIFI: 2.4 GHz 3T3R integrated
> 5 GHz 3T3R QCA9890 oversized Mini PCIe card
> Ethernet: 2x 10/100/1000 Mbps QCA8334
> port labeled LAN1 is PoE capable (802.3at)
> USB: 1x 2.0
> LEDs: 7x which two are GPIO controlled, four switch controlled, one
> controlled by wireless driver
> Buttons: 1x GPIO controlled
> Serial: RJ-45 port, Cisco pinout
> baud: 115200, parity: none, flow control: none
> JTAG: Yes, pins marked J1 on PCB
>
> Installation
> 1. Prepare TFTP server with OpenWrt initramfs-kernel image.
> 2. Connect to one of LAN ports.
> 3. Connect to serial port.
> 4. Power on the device and when prompted to stop autoboot, hit any key.
> 5. Adjust "ipaddr" and "serverip" addresses in U-Boot environment, use
> 'setenv' to do that, then run following commands:
> tftpboot 0x81000000 <openwrt_initramfs-kernel_image_name>
> bootm 0x81000000
> 6. Wait about 1 minute for OpenWrt to boot.
> 7. Transfer OpenWrt sysupgrade image to /tmp directory and flash it
> with:
> sysupgrade -n /tmp/<openwrt_sysupgrade_image_name>
> 8. After flashing, the access point will reboot to OpenWrt. Wait few
> minutes, until the Power LED stops blinking, then it's ready for
> configuration.
>
> Known issues
> Green power LED does not work.
>
> Additional information
> The U-Boot fails to initialise ethernet ports correctly when a UART adapter is
> attached to UART pins (marked J3 on PCB).

phy-mode is already set in qca955x.dtsi and can be removed here.

Please add comments here to help the reader, like other devices do, e.g.:
qca,ar8327-initvals = <
0x04 0x87600000 /* PORT0 PAD MODE CTRL */
0x0c 0x00080080 /* PORT6 PAD MODE CTRL */
0x7c 0x0000007e /* PORT0_STATUS */
0x94 0x0000007e /* PORT6 STATUS */
>;
I have not reviewed the values, so hopefully they are correct.
